QUESTION

The mean height of women in a country (age 20-29) is 63.9 inches. A random sample of 50 women in this age group is selected.

  • The mean height of women in a country (age 20-29) is 63.9 inches. A random sample of 50 women in this age group is selected. What is the probability that he mean height for the sample is greater than 65 inches? Assume a= 2.67.  (i put an "a" because i could not figure out how to put the symbol that was used in this question for my homework but it looks like a lower case "a" that was turned on its left side)
  • The probability that the mean height for the sample is greater than 65 inches is  ????
  • (round to four decimal places as needed)
P (X > 65)Normal Distribution, µ = 63.9, σ = 2.67, n = 50x − µxx−µ√we convert this to standard normal using z ==σxσ/ n65 − (63.9)√z=≈ 2.913174 ≈ 2.912.67/ 50P...
